This map shows modeled outdoor noise across Clarksville at 100-meter resolution, combining road, aviation, and rail sources. Green areas measure below 45 dBA. Orange and red exceed the EPA's 55 dBA outdoor threshold linked to long-term health effects. Use the layer toggles to view each source on its own or all together.

Population Above the EPA Outdoor Threshold
The EPA's 55 dBA outdoor reference level is a common benchmark for residential noise exposure, especially for activity interference, annoyance, and long-term community noise concerns. About 258 Clarksville residents, or 7.3%, live above that level. By land area, 16.5% of Clarksville is above 55 dBA.

Noise by Part of Clarksville
Average noise levels for Clarksville residents, grouped by direction from the center of Clarksville. Western Clarksville carries the highest population-weighted average; Eastern Clarksville carries the lowest. Just 2% of residents in Eastern Clarksville live in blocks above the EPA's 55 dBA threshold, a fifth of the share in Western Clarksville.
Central Clarksville
6% of people above 55 dBA
Eastern Clarksville
2% of people above 55 dBA
Northern Clarksville
9% of people above 55 dBA
Southern Clarksville
4% of people above 55 dBA
Western Clarksville
11% of people above 55 dBA
Western Clarksville sounds about 116% louder than Eastern Clarksville to the human ear, a 11.1 dBA gap. Every 10 dBA roughly doubles perceived loudness. Within any of these directions, two homes a quarter mile apart can still differ by 10 or more dBA depending on how close they sit to a major highway.
How far back from Bluestone Wma Rd do you need to be?
Bluestone Wma Rd produces an estimated 57 dBA at its loudest centerline points. Noise drops logarithmically with distance, with the exact rate depending on what's between you and the road. Tree cover, walls, terrain, and pavement type all matter. At roughly a quarter mile back, traffic fades into the noise level of a soft rainfall.
Calculated from the model's calibrated attenuation formula. About 62% of Clarksville sits under tree canopy (much heavier than most cities) and roughly 4% is impervious surface like pavement and rooftops. Both are folded into the per-place decay rate above. Heavier canopy pulls noise down faster with distance; impervious surfaces slow the drop.
